Don't know about Kotu, the red around the face is unusual.
Gratsby could be Cochin or Brahma, depending on how that comb develops.
Cheep and Squirckle need to be feathered in before I can even try to guess. So many breeds look like that as chicks.
Lily might be a Leghorn.

I thought Kotu may be an Australorp. And we looked at a couple different sights to try and identify the two "chipmunks" and, like junebuggena said, there were like seven different species they could be We purchased them this past Friday from a local feed store and they are growing like weeds. Their wing feathers are already coming in. Thank you so much!

OK! I called the feed store and they could only remember three breeds they had. Black Sex Link, Buff Orpington, and White Leghorn. That helps with Kotu the Black Sex Link. From what google says the White Leghorn and Orpington chicks kinda look the same. I'm hoping the chipmunks turn out to be Welsummers.
